Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

I have a number of Windows 2012 Hyper-V hosts running Server Core.  These hosts haven't been patched since they were installed back in 2016.  I've just checked and these hosts only have 25GB of free space, is there a way of checking (even a rough estimate) what the size of the update download to these servers will be?  The updates will be deployed via WSUS and GPO.  Thanks.
I have a number of Hyper-V servers running Windows 2012 Core which have not been patched in some time.  Can I just patch the Hyper-V hosts or do I need to patch the VM's as well.  

For background, this is a legacy environment and they people that built it have left the company some time ago without any handover.  Windows Update service has been disabled on all the vm's for some reason.  The vm's are a mix of Windows 7 and Windows 2008R2.

Is it just enough to patch the Hyper-V hosts?
need some advice on building  Hyper-V host.  I think my biggest concern is the Processor.  Type of drives I do not believe is critical because they are VM's.

VM's will be
A Microsoft Access database server
File Server
Citrix server
Backup server
SQL server
Print server
Hi, I was trying to use Microsoft Virtual Machine Converter to P2V and when it ask for credentials it fails out.

Im dooing this from the computer I want to convert.  

Question can you convert from the physical computer, or do I have to do it from a third computer?  With VMWare converter I can do it from the local computer

Thanks all
I am running Hyper-V  on Svr 2012 R2.
I rebooted the host after installing visual c++ 2015 Redistributable.

when it came back up i saw my VMs stuck in a "Saved" state.
when i try to start the VMs i get the error
"An error occurred while attempting to change the state of virtual machine"
"'Hostname' failed to initialize.

I tried deleting the saved state, but got the same error as noted above.

i check the event viewer and see event IDs 14070 and 15120.

I am also getting error with event ID 1000 as shown below.

I am looking for someone who can name an nvidia card that can be used with Hyper-V's discrete device assignment (DDA), that has a small form factor, because the server mainboard allows a maximum length of 180mm.
Which ones could I take? Max price is 500 USD.
Hi, we have just had Avaya IP Office and Voicemail Pro installed on a Hyper-V Virtual Server (A Dell Poweredge R7040 with 32GB RAM Intel Xeon Silver 4109T 2Ghz (2 Processors). The Avaya virtual server has been running fine since Christmas but over Easter it crashed. The telecoms guys that support it say that for 1-100 users it should be at least a 4 Ghz Processor (we have 75 users) and 2-3 cores.

Now, I can shut it down tonight and give it an extra processor, but would we really need to upgrade the processors to faster ones? It's a fairly new server and I thought that the Xeon Silver 4109T although low Ghz are pretty good? Thanks for the help.
Hi Guys,

I would like to setup replication and recovery for an Exchange 2016 server running on VM (Hyper-V).

The two options I am currently investigating is setting up
1.  Hyper-V Replication to another site (VM), or
2.  MS Exchange DAG to another site

Has anyone perhaps explored or setup both options, and which works the best as a long term solution?
Windows Server 2012 (non-R2) Hyper-V Failover Cluster
--four host node servers
--iSCSI cluster shared volumes (NetApp SAN)
--four VLANs
--80 hosted VMs

Upgrade the failover cluster to Windows Server 2019.

We're aware of the need to evict one or more nodes to build a "new" cluster with WinSrv2019, then connect the storage and "swing" the VMs over (a procedure no longer needed when upgrading a WinSrv2012-R2 or later cluster).

--Can we perform the old-school "evict & build new" steps to upgrade straight to Windows Server 2019?  
--Or, is it advised to first upgrade from 2012 to 2012-R2, then perform rolling upgrades to 2019?
--If we upgrade straight to 2019, are there any known issues or "gotchas" to watch out for due to skipping 2012-R2 and/or 2016?
--Are there any documentation or white papers for upgrading from 2012 (non-R2) failover clustering straight to 2016/2019?  (Finding the docs just for 2012-2012R2 are difficult as it is.)

More info available upon request.  Thanks in advance for assistance.

What is the correct way to licence this Hyper-V situation?

Existing Server 2012 running Hyper-V, licenced. Server has 4 VMs, also licenced. The server is getting old and is going to be made into a replication server for DR purposes.
We want to introduce another Hyper-V running Server 2019 and replicate the existing (licenced) VMs onto the new server.

At no point will the VMs be running on more than one server.
Do we just need one Server 2019 licence to get the Hyper-V covered?
Dear Experts,
Creating a disk partition via disk management utility  on virtual machine that runs on hyper visor is same as the the physical machine???? Last time I created the partition of VM that run on hyper v. I found the the new partition created on my physical machine automatically. It was little confusing. Can you throw some light on this issue??

VM is windows server 2016.

Many thanks for your valuable advice in advance

 I have a new server with two INTEL XEON SILVER 4110 @2.1GHZ 8 Core CPUs on MB and like to know how many Windows Server 2019 standard license that I need to purchase.
 I am going to create three virtual machines in Hyper-V server.
 As I understand it, each server license covers two VMs, so I need total two server licenses and end user CALs?

I have a single domain controller which runs in a virtual machine hosted by Hyper-V server 2019 which is a domain member but only runs server core i.e. command line and powershell. My dc is showing as started though I believe the boot is actually failing. I cannot get any further because I cannot connect Hyper-V manager to the Hyper-V server because domain connectivity is screwed up since my only DC is down - no DNS , no Active Directory, no authentication etc.. How can I fix the boot problem my dc is suffereing from when I do not have any access to it.  I WAS in the process of setting up a second dc on another physical machine as part of a migration to Server 2019.  Now I'm stuck.
Hi Guys,

We have a mission critical server on a Hyper-V (VM) for which I would like to run an export to have a copy of the original machine.

I will be doing the export, while the server is running and high in demand.

The server / services can't be affected in any way.
Has anyone experienced any issues with exporting a VM from a running server, or is this absolutely safe to do?
I have a client with a single server acting as both DC and file server that needs replacement. Approximately 20 users with AutoCAD storage. We can build new server on bare metal but are considering Hyper-v hosting 2 VMs, one for the DC and the other as file server.

Thoughts on pros and cons?
Configuring Exchange under W2016 Hype-v.  Here are a couple of questions:

1. Must Exchange run as it own guest Hyper-V ?  Limit cores to 12 cores?  Ram to configure?   12 users Exchange

2. We are migrating to W2016 from SBS 2011.  Will standard migration run porting over older Exchange to 2016?


 I am setting up Terminal (Remote Desktop) Server in Windows 2019 Hyper-V environment.
 I created two virtual machines (DC1: domain controller and APP1: to run application software like Quickbooks, Word, Excel, Outlook) and they are running Windows 2019 OS as well.
 My question is which computer should I install Remote Desktop components on between DC1 and APP1:
Remote Desktop Session Host
Remote Desktop Connection Broker
Remote Desktop Gateway
Remote Desktop Web Access
Remote Desktop Licensing

This system is for 2 users to connect remotely and run applications programs on APP1 VM. I may not need all the components listed above, but like to know which VM is better suited for it.

Dear Experts,

It might be stupid question but I need to ask. Can I supply product key of windows server 2016 standard edition  to Windows server 2016 Data center edition Evaluation. Will it automatically down grade the installed Data center edition to standard edition or OS will refuse to accept the standard edition product key. Please share your experiences Thanks

Running Hyper-v from USB?  I've does this many times with VMware and it works great.  I know it can be done with Hyper-V but are there any fallbacks?  Any major performance restrictions?
Experts!  So I'm at a new company and need we have a mix of VMWAre and Hyper-v.  Trying to work with what I have.  It's breen a while since Ive really done anything with Hyper V.  Is there a good vSan alternative with Hyper-v?  

Also in regards to cost.  I shoudl be able to re-pupose current server hosts to create two 3 Host Clusters, one for each location.  Expecting 8 Guest VMs per site.   What in your experiance is more cost effective?  I would like HA and vMotion features so if I were to go with:

- VMWare would need standard plus (10k to 14K with support? plus Windows Serve licencing 3 Hosts * 8 guests = 24 Server Licences per site).  
- Hyper-V not sure but should be able to get away with Server Enterprise (3 Enteprise allow for 4 hosts so I would need 6 Enterprise Server Lic?).    vSan needed for now till I can re-pupose existing NAS (1 for each of my two sites).

Am I missing anything obious?  I have more experiance with VMWare but I know Hyper-V has come a long way and I don't need any features besides what I mentioned.  

When trying to move virtual machine storage to a new disk in  hyper-v failover cluster manager, I get permission error. All of those disks are showing as available in the failover cluster disks (volumes).
Need some advice on how to do a license calculations for Hyper V Cluster environments? Thanks.
Hello Experts,

We are migrating a lot of windows 2008 R2 stand alone servers, some with hyper-v.  The VM's are running the same OS.  Is there any third party software that can move all of the roles, features and any software currently installed to a newer server such as Windows Server 2016 or 2019?  I haven't really heard of something like this but figured this would be the best place to ask first.

thank you,

I'm setting up Windows Server 2016 Standard.
My objective is to have 2 VMs that are connected into their own subnet for a testbed.
I've read about the internal switches, etc. but don't see how to make a physical connection to each of the subnets AND be independent.
(Perhaps the testbed objectives are a bit different than a typical production network).
I am imagining adding a couple of NICs so there will be:
A NIC for the Hyper-V manager.
A NIC for each of the subnets.

A nudge in the right direction would help a lot!
Last year we did a few things starting with: https://www.experts-exchange.com/questions/29064169/Introducing-Windows-Server.html
Next, one of the Experts engaged in a planning task for us that was tailored to our particular situation; the result was an outline of an approach that makes sense to *me* and I'll be revisiting that soon.
Next, I set up a test lab with Windows Server 2016 Hyper-V VMs.  Not that I *plan* to have two servers per site but that I *anticipate* the possibility.
That's going to be revved up now and I'll probably configure a 2-subnet arrangement with a DC out of the 2 VMs on each.  That will do a pretty good job of emulating the real environment.
(I'm a rather great believer in partitioning machine roles and in keeping things simple to understand as much as is possible).

Some had asked what we are trying to accomplish:
- We aren't trying to implement file serving up front because we already have a pretty good system set up for that and it's not the focus.  BUT, I'm willing to consider it.  And that's the purpose of THIS question.
- We need to provide User and Access controls - that's the focus.  And, I'm hoping to grease the skids for things like SIEM that we now do sans-server.  Keeping individual machines "connected" either passively or with agents still proves to be challenging.  There are always a handful of machines that don't respond - even after ALL the machines have been made responsive.  I suspect Windows updates more than anything has …
